Effect of variable load on crack initiation microalloyed steel S 690-QL

open access: yesMetalurgija, 2015
The accumulation of damage in the form of initiation and growth of micro-cracks is the first stage of destruction that ends when the merger microcracks form macro cracks. Cracks formed in the cycle number N =104 - 105 are the result of low cycle fatigue.

Vacuum thermal-mechanical fatigue testing of two iron base high temperature alloys [PDF]

open access: yes
Ultrahigh vacuum elevated temperature low cycle fatigue and thermal fatigue tests of 304 stainless steel and A-286 alloy have shown significant effects of frequency and combined temperature-strain cycling on fatigue life.

Finite element analyses of fatigue crack growth under small scale yielding conditions modelled with a cyclic cohesive zone approach [PDF]

open access: yes, 2013
Mode I fatigue crack growth is modelled and investigated with a cohesive zone approach. A 2D finite element boundary layer model under plane strain and small scale yielding conditions is used to generate fatigue crack growth rate curves ...

Crystal plasticity simulation of the effect of grain size on the fatigue behavior of polycrystalline Inconel 718

open access: yes, 2018
A microstructure-based model that accounts for the effect of grain size has been developed to study the effect of grain size on the fatigue life of Inconel 718 alloys.

MAGTWIST: A Magnetically‐Driven Rotary Actuator Using a Traveling‐Wave With Integrated Stiffness Tunability

open access: yesAdvanced Functional Materials, EarlyView.
MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Biomaterials‐Based Hydrogel with Superior Bio‐Mimetic Ionic Conductivity and Tissue‐Matching Softness for Bioelectronics

open access: yesAdvanced Functional Materials, EarlyView.
By mimicking the ion‐accelerating effect of ion channel receptors in neuron membranes, a biomaterials‐based ionic hydrogel (BIH) is developed, which offers a high ionic conductivity of 7.04 S m−1, outperforming conventional chitosan, cellulose, agarose, starch, and gelatin based ionic hydrogels.
